In one embodiment, the control host 14 may compare the first physical action with the second physical action to obtain the difference between the first physical action and the second physical action. This difference can be reflected in the movement trajectory of the handheld guiding device 11 when the first physical action is performed and the movement trajectory of the ultrasonic scanning device 13 when the second physical action is performed. Specifically, the handheld guiding device 11 generates a first inertial measurement signal according to the motion of the first entity, and transmits the first inertial measurement signal to the control host 14, and the ultrasonic scanning device 13 generates a second inertial measurement signal according to the motion of the second entity, and transmits the second inertial measurement signal to the control host 14, so the control host 14 can determine whether the difference between the first entity action and the second entity action conforms to a warning condition according to the first inertial measurement signal and the second inertial measurement signal . In response to the difference between the first entity action and the second entity action meeting the alert condition, the control host 14 may instruct the prompting device 15 to output alert information.

In one embodiment, the control host 14 can store the ultrasonic image 102 captured by the ultrasonic scanning device 13 . For example, the ultrasound image 102 may be stored in the memory circuit 22 of the control host 14 . However, in one embodiment, the warning condition is met in response to the difference between the first physical action and the second physical action (for example, the movement trajectory when the handheld guiding device 11 performs the first physical action and the ultrasonic scanning device 13 performs the second physical action). When the difference between the movement trajectories of the entity exceeds the allowable value), the control host 14 can discard and store the current ultrasonic image 102 from the ultrasonic scanning device 13 . For example, when it is determined that the ultrasound image 102 can be discarded, the processor 23 of the control host 14 may not store the ultrasound image 102 in the storage circuit 22 or delete the ultrasound image 102 from the storage circuit 22 . In this way, when the moving trajectory of the ultrasonic scanning device 13 deviates too far from the preset trajectory (ie, the moving trajectory of the handheld guide device 11 ), the useless ultrasonic images 102 are continuously stored and occupy the storage space of the storage circuit 22 .

In one embodiment, in response to the difference between the first entity action and the second entity action meeting the alert condition, the control host 14 may instruct the prompting device 15 to present the navigation correction information. This navigation correction information is suitable for correcting the movement trajectory of the ultrasonic scanning device 13 . For example, this navigation correction information may be presented in a screen displayed on the display of the prompting device 15 . For example, the processor 23 of the control host 14 can send an instruction message to the prompting device 15 via the communication interface 21 . According to the command message, the prompting device 15 can output the navigation correction information.

In one embodiment, this navigation correction information can also be presented via light 103 . For example, the color or brightness characteristics of the light 103 such as the color, brightness, flickering frequency, etc., can be changed according to the navigation correction information, so as to warn the operator of the ultrasonic scanning device 13 that the ultrasonic scanning device 13 must move in a specific direction or change the direction of the ultrasonic scanning device 13 direction of movement.

In this way, the control host 14 can obtain the movement trajectory of the handheld guiding device 61 when performing the first physical action (for example, the distance, depth or inclination angle of pressing down toward the soft material layer 602 ) according to the first inertial measurement signal, and generate corresponding navigation prompt information 101. Then, the control host 14 can guide the operator of the ultrasonic scanning device 13 to perform a similar second physical action such as pressing or tilting through the navigation prompt information 101 .
